Description

Technical Field

[0001] The present invention relates to a coffee machine and a corresponding management method which in particular allow facilitating and accelerating the use of the machine by the user. Background Art

[0002] Modern coffee machines comprise a control unit provided with a processor and a user interface equipped with at least one information display and a series of keys, also of the touch screen type, by means of which the type of beverage to be prepared using the coffee machine can be selected.

[0003] These modern coffee machines are capable of producing quite a number of beverages, such as espresso, milky coffee or latte, Americano, cappuccino or other beverages, and can also change some parameters of these beverages, such as quantity, aroma, etc., as desired.

[0004] Therefore, the display of these user interfaces is usually provided with a beverage selection menu and the desired parameters have to be set for each beverage.

[0005] Each time the user takes some time to select the desired beverage and the corresponding parameters, even if he / she generally tends to consume a specific beverage more frequently, both in an absolute sense and taking into account different times of the day. For example, it is possible that the same user may habitually drink a first beverage in the morning and may habitually drink a second beverage in the afternoon, etc. Thus, user habits may be similar from one day to the next.

[0006] Thus, known coffee machines tend to repeat certain beverage selection operations several times within a day or day after day, making them time-consuming and laborious to use.

[0007] If the coffee machine is located, for example, in an office, where a number of different users have to select their own beverages, the time required to select the desired beverage can also become a serious problem.

[0008] Furthermore, prolonged use of the coffee machine and the corresponding degree of effort in its operation for selecting frequently desired beverages results in an undesirable consumption of electrical energy.

[0009] Document US2021 / 235921A1 describes a machine for preparing beverages, which provides for monitoring a plurality of data during the preparation of the beverage and storing them in a server together with data relating to a specific user and a possible evaluation of the beverage by the user, and provides for graphically displaying on a display the preferences expressed by the user over a determined time interval regarding the organoleptic properties of the beverage in terms of taste, aroma, etc. In this way, the user can see whether and how their taste preferences change over time.

[0010] Document US 2014 / 166703 A1 describes a device for dispensing liquid condiments based on information obtained from a cooking guide system connected to the Internet, in order to facilitate the preparation of certain recipes by the user.

[0011] Therefore, there is a need to improve a coffee machine and a corresponding management method, which can overcome at least one disadvantage of the prior art.

[0012] In particular, it is an object of the present invention to provide a coffee machine that is simpler and more intuitive to use.

[0013] Another object of the invention is to provide a coffee machine with which a commonly desired beverage can be selected more quickly than with known machines.

[0014] Another object of the present invention is to provide a coffee machine that limits the number of uses and the effort of the operations performed by the user to select a beverage.

[0015] Another object is also to provide a machine which also allows energy savings to be obtained due to the fact that it requires fewer choices and commands from the user.

[0016] Another object of the invention is to perfect an effective and simple method for managing a coffee machine.

[0017] The Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages. Summary of the invention

[0019] In accordance with the above objectives, the coffee machine according to the invention comprises a control unit provided with a processor and connected to a user interface provided with at least one display for displaying a dispensable beverage.

[0020] According to a characteristic aspect of the present invention, the control unit includes at least one data storage module, which is configured to automatically store at least information related to a beverage selected by a user through a user interface within a determined time interval and a timestamp related to the moment of selection of such a beverage, and the control unit is configured to process multiple lists of selected beverages respectively associated with time ranges predefined according to the timestamps, and is configured to display a beverage associated with one of the lists on a display based on the time interval and the time range corresponding to the list.

[0021] In this way, a determined list is displayed each time, depending on the moment at which the user requests the optional beverages to be displayed.

[0022] According to some embodiments, the beverages present in one list are different than the beverages present in the other list and / or are ordered differently in one list or the other.

[0023] Since a plurality of lists are displayed, which are differentiated with respect to a certain time range and are related to his / her habits, the user has direct access to the beverages he / she likes within the determined time range and can therefore select the desired beverage in a very simple and quick manner.

[0024] According to another aspect of the present invention, the data storage module is also configured to store at least the frequency of users selecting certain beverages within a certain time interval, and is configured to process the list to sort the beverages based on the stored selection frequency, thereby highlighting the most selected beverages in each time range.

[0025] Owing to show a plurality of lists of the beverages that are most frequently selected, the present coffee machine advantageously allows simple and intuitive use.In fact, the beverage that is usually desired at a certain moment of the day can be selected faster than that occurring in known machines.

[0026] Thus, the time of using the coffee machine is advantageously reduced, as well as the effort required to perform the operations to select a beverage, making the machine more comfortable and faster for the user.

[0027] Furthermore, since the time required to select a beverage is shorter, the display can remain on for a shorter period of time, also allowing energy savings to be achieved.

[0042] - Figures 2 to 8 is a view of the displays provided in the user interface of the coffee machine in various data display situations.

[0043] It must be clear that in the present description, the words and terms used, as well as the figures in the accompanying drawings as mentioned, have the sole function of better illustrating and explaining the present invention, their function being to provide a non-limiting example of the invention itself, since the scope of protection is defined by the claims.

[0044] To facilitate understanding, where possible, the same reference numerals have been used to identify the same common elements in the drawings. It should be understood that elements and features of one embodiment may be conveniently combined or incorporated into other embodiments without further explanation. DETAILED DESCRIPTION

[0045] Now we will refer in detail to possible embodiments of the present invention, one or more examples of which are shown in the accompanying drawings by way of non-limiting illustration. The phraseology and terminology used herein is also for the purpose of providing non-limiting examples.

[0046] With reference to the drawings, in particular to Figure 1 , the coffee machine 10 comprises a control unit 11 provided with a processor 12 and connected to a user interface 13 provided with at least one display 14 for displaying the dispensable beverages B1 , B2, B3 . . . Bn.

[0047] The control unit 11 comprises at least one data storage module 15 configured to store at least information about beverages B1 , B2, B3 ... Bn selected by the user within determined time intervals, for example during a day, a week or even a month.

[0048] In particular, the data storage module 15 is configured to store information including both the selected beverage and the timestamp associated with the moment of selecting such a beverage. For example, each time a beverage is selected, the time and / or the date of the week, etc. may also be stored.

[0049] The detection and storage of the above information by the data storage module 15 is automatically performed each time the user selects a beverage to be prepared.

[0050] The control unit 11 is configured to process a plurality of lists 16 of selected beverages respectively associated with predefined time ranges of the considered time interval. Figure 4 )、17、18( Figure 5 and Figure 6 ) and display them in different sorts on the display 14 based on the time range.

[0051] In other words, depending on the moment, that is to say the moment at which the display of a beverage on the display 14 is requested, the control unit 11 selects the beverage associated with the list 16 , 17 , 18 corresponding to the time range to which the moment belongs and displays it on the display 14 .

[0052] Based on the data stored in the data storage module 15, the control unit 11 can also automatically associate beverages with the respective time ranges and thus update the respective lists 16, 17, 18 accordingly.

[0053] For example, one or more time ranges may be defined, and the control unit 11 may determine which beverages to select for each time range based on information stored in the data storage module 15, and may also determine the number of times such beverages are selected.

[0054] The respective start time and end time for each time range may be stored in the storage module 15 .

[0055] According to a possible embodiment, the time range may correspond to individual time periods into which a day may be divided, such as "morning", "afternoon", "evening", or to one or more days of the week, considered individually such as "Monday", "Tuesday" etc., or divided into groups such as "weekdays" and "holidays", or even related to individual weeks, for example in case the user works two or three different shifts.

[0056] According to some embodiments, these time ranges may be defined during the design phase and stored in a memory unit of the machine 10, such as in the data storage module 15, or they may be entered and / or modified by a user, for example via the user interface 13 or a processor 29 (e.g. a smartphone, tablet computer, etc.) on which a dedicated software application is installed.

[0057] In particular, it can be provided that the user can modify at least the start time and the end time of one or more time ranges.

[0058] According to some embodiments, the data storage module 15 is further configured to store at least the frequency of selection of a determined beverage B1, B2, B3 ... Bn by the user via the user interface 13 within a determined time interval, for example during the course of a day, or in each time period provided, and the control unit 11 is configured to process at least one list of beverages based on said selection frequency, see e.g. Figure 4 List of 16 or Figure 5 and Figure 6 Any of the other lists 17 and 18 of the display 14 is then presented to highlight the most selected beverages in each time range.

[0059] In this way, not only are beverages Bl, B2, B3 ... Bn typically selected within each time range displayed for each time range, but the beverages are also ordered based on the number of times they have been selected by the user.

[0060] This display mode helps make the use of the machine 10 more convenient and faster.

[0061] According to some embodiments, the time interval considered for evaluating the selection frequency may be the entire interval that has passed since first power-on or since a reset of the machine 10, or only a limited period of time, such as a few weeks or months, may be considered. This second option allows the display to be adjusted in a more dynamic way with respect to possible changes in user preferences.

[0062] At least one list 16 includes a plurality of beverages, see for example Figure 4 Beverages B1, B2, B3, ... Bn are sorted in descending order based on the frequency of selection, so that the beverage B1 that appears at the beginning of the list 16 is the beverage that the user has selected most during the determined time period, while beverages Bn are beverages that are selected less frequently. Of course, the list 16 may include a greater or lesser number of beverages based on the number of beverages that the coffee machine 10 is capable of producing.

[0063] According to some embodiments, the mode for displaying beverages according to a defined time range can be activated by the user by a corresponding command 19 shown on the display 14. This command 19 can be a two-position virtual key located on the display 14 of touch screen type, for example.

[0064] When this display mode is activated, the list 16, 17, 18 to be displayed is automatically determined by the control unit as a function of the current time.

[0065] Therefore, it can be assumed that, when started, the coffee machine 10 presents Figure 2 The screen of the coffee machine 10 is displayed and allows the beverage display function to be selected according to the beverage list that is usually selected. If the command 19 is not activated, the coffee machine 10 works in a conventional manner. Otherwise, by means of an additional command 20, it is possible to proceed to the next screen.

[0066] The next screen can be directly Figure 4 , 5 , 6, one of the lists 16, 17, 18, or Figure 3 A screen in which a list of time ranges, in particular a list of time ranges associated with a determined user profile, is shown, and the currently used time range is highlighted, ie the period corresponding to the moment when the display is performed is highlighted.

[0067] In the case of time ranges associated with user profiles, for each of them a respective start time and end time may be stored in the storage module 15 , which may be fixed for all profiles or modifiable by the user, for example by means of the processor 29 .

[0068] According to some embodiments, there may also be a plurality of different commands 21, 22, 23, in the example case three, that is, one for each time range, which allow the selection of a corresponding list 16, 17, 18 of beverages so that information relating to them can be viewed. In this way, the user can, for example, modify the start and end moments of one or more time ranges, change their names, or can add new time ranges.

[0069] Preferably, a list 16 , 17 or 18 associated with a certain time range is automatically shown on the display 14 based on the current date or time which can be easily evaluated by the control unit 11 .

[0070] These different lists 16 , 17 , 18 may refer to different time periods of the day, for example, list 16 may refer to the morning time period, list 17 may refer to the afternoon time period, and list 18 may refer to the evening time period.

[0071] For example, the morning period may vary from 6 am to 12 pm, the afternoon period may vary from 12 pm to 6 pm, and the evening period may vary from 8 pm to midnight.

[0072] For example, in Figure 3 In the screen shown, the "morning" session will be indicated as being activated at 10.00 am, while the "afternoon" session will be activated at 15.00 pm.

[0073] According to some embodiments, a functionality may be provided that allows the user to change the time periods at will via the display 14 or processor 29 to change the number of lists during the course of a day, for example to have a single list for the entire day, or to divide the day into more than three time periods, etc., for example to change the type of time range considered, based on daily, weekly, monthly, etc.

[0074] According to some embodiments, when the automatic display of the lists is set, for example after receiving a command to activate the display 14 or to prepare a new beverage, the respective lists 16, 17, 18 are displayed according to time.

[0075] In the example case, if the current time belongs to the morning period, list 16 is displayed, if the current time belongs to the afternoon period, list 17 is displayed, and if the current time belongs to the evening period, list 18 is displayed.

[0076] Furthermore, within each list, the order of the beverages is defined based on the number of times they have been previously selected for each time frame.

[0077] For example, let us assume that in the list 16 relating to the morning time period, the beverage most selected by users is beverage B1 , and therefore it is highlighted at the top of the list 16 .

[0078] In the list 17 related to the afternoon time period, the beverage most selected by users is beverage B3 , and thus it is highlighted at the top of the list 17 .

[0079] In the list 18 associated with the evening time period, the beverage most selected by users is beverage Bn, and therefore it is highlighted at the top of the list 18 .

[0080] The user, based on the time period during which he / she wants to use the machine 10 to prepare beverages, will obtain a list 16, 17 or 18 having at the top the beverages B1, B2, B3...Bn that he / she usually drinks during that time period of the day, so that he / she can quickly and easily select the beverage that is usually consumed, instead of scrolling through the machine's menu each time and setting the type and parameters of the beverage.

[0081] Some parameters of each beverage B1, B2, B3 or Bn can also be displayed, such as the amount, which may be small, medium or large, see label 24, the degree of aroma of the coffee, etc.

[0082] Furthermore, these customized parameters may be stored in the data storage module 15 in such a way that each beverage displayed in the respective lists 16, 17, 18 comprises its own customized parameters, depending on the respective time range considered. Thus, an "espresso" beverage for a given time range may, for example, comprise a "strong" taste and a "large" amount as parameters, while an "espresso" beverage for another time range may comprise a "mild" taste and a "medium" amount as parameters, and so on.

[0083] On each screen associated with lists 16, 17 and 18, additional commands and labels may also be provided, such as a label 25 indicating a user name, a label 26 indicating a time period, a command 27 for returning to a general screen, a command 28 for allowing access to settings, and the like.

[0084] Each of the images of the beverages B1, B2, B3 and Bn of the respective lists 16, 17, 18 is associated with a command, so by pressing on the image, the coffee machine 10 starts preparing the selected beverage. For example, if the beverage B1 is pressed, the coffee machine 10 starts preparing it and its parameters (e.g. quantity, aroma, etc.) will automatically be the last set parameters.

[0085] The user can change the parameters of the determined beverage before preparing the beverage, for example by pressing command 28 and through another screen (not shown) of display 14. When the selected beverage is ready, a screen appears. Figure 7 , which allows saving the current settings of the list of which the selected and prepared beverage is part by command 30. If the user decides to save the settings by checking the box 31 and pressing command 32, the list 16, i.e. the list associated with the current time range, is updated and saved. Alternatively, the beverage parameters can be retained as present in the last saved list.

[0086] The coffee machine 10 can be operated naturally without this mode of displaying one or more favorite and habitually used lists 16, 17, 18 by deselecting this function via an appropriate command 33 via a screen that can be accessed, for example, via a settings command 28, see for example Figure 8 .

[0087] In this case, beverages B1 , B2, B3, Bn are dispensed with default parameters of the coffee machine 10, which parameters can be modified each time, and no preference list is presented for beverage selection.

[0088] According to a possible embodiment, it can be provided that, with the time-period display function disabled, on the display 14 the optional beverages B1, B2, B3, Bn are in any case displayed according to how often they were selected, sorted in a customized manner based on a defined user profile or based on the overall selections made by all users.

[0089] According to some embodiments, the control unit 11 may also include a wireless communication module 34 configured to allow data exchange with a processor 29 owned by the user, even remotely.

[0090] The display and time range setting functions may be accessed remotely via an application installed on the processor 29 , whereby the control unit 11 may then define the one or more lists 16 , 17 , 18 .

[0091] For example, functionality may be provided that allows the processor 29 to set and change the start and end of a predefined time range, such as the start and end time of a time period that may be displayed.

[0092] Another function that can be implemented in the application installed on the processor 29 is to change the names of various time ranges, or to change the time ranges according to the day of the week, for example the weekday time range can be different from the public holiday time range, etc.

[0093] Another function that can be implemented in the application installed on the processor 29 can be, for example, remotely varying the parameters of the various beverages B1 , B2 , B3 , Bn, thus varying their quantities or the like.

[0094] If there are multiple users of the coffee machine 10, through the application installed on the processor 29, it is also possible to select the user's own profile or use one of the profiles of the machine 10 and then view the preferences of the determined profile on the display 14 and therefore finally view the one or more lists 16, 17, 18.

[0095] The selected beverages B1, B2, B3 ... Bn may be stored, for example, in a specific user profile associated with a specific user. For example, the user profile may be made available after selecting the user profile on the user interface 13, or after identifying the user himself, for example by scanning a code with an optical reader or the like, or by wireless communication between the processor 29 and the control unit 11.

[0096] Therefore, a method for managing a coffee machine 10 comprises: storing at least information about beverages selected by a user via a user interface 13 within a determined time interval and a timestamp associated with the moment of selection of such a beverage; processing a list of multiple selected beverages respectively associated with a time range predefined according to the timestamp; and, displaying the beverages in the lists 16, 17, 18 on a display 14, these beverages being sorted in different ways based on the current time range.

[0097] According to one aspect of the invention, the management method provides for storing at least the frequency with which a user selects a certain beverage via the user interface 13 within a certain time interval, that is, within each time range, processing at least one beverage list, such as one of the lists 16, 17 or 18, based on the selection frequency, and displaying the at least one list on the display 14 to highlight the most selected beverage for each time range.

[0098] It is clear that modifications and / or additions of components may be made to the coffee machine 10 described above without departing from the sphere and scope of the present invention as defined by the claims.

[0099] It is also clear that, although the invention has been described with reference to a few specific examples, those skilled in the art will of course be able to implement many other equivalent forms of coffee machines, all of which fall within the field and scope of the invention.

[0100] In the following claims, the only purpose of references in parentheses is to facilitate reading and they shall not be construed as limiting factors with respect to the field of protection defined by the claims.
